To (1,77 whom, t may concern:

Be it known that we, JOHN .W. LUTZ and CLARENCE O. LUTZ, citizens of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented l certain new and useful Improvements in Tool-Holders, of which the following is Ia specification, reference being had therein to the accompanying drawings.

This invention relates to tool-holders, and has for its object to rovide a simple and eilicient tool-holder W ereby a working tool or instrumentality, such as a scraper or file, may be detachably held-in any desired angular relation to the handle portion of the tool, thc connection between the tool-clamp and handle portion of the holder being suchthat th(` too -clamp may be readily disconnected from the handle portion and another toolr-lanip of a different character ada ted to holdV a working tool, of a different 'nd be readily substituted therefor.

To these and other ends the invention consists in certain novel features, which we will now proceed to describe and will then` particularly pointlout in the claims,

In the accompanying drawings, Figure lis a plan view of a tool-holder embodying our invention in one form, the same being shown with a scraper and its tool-clamp applied thereto. Fig. 2 is a longitudinal sectlonal view of a portion ofthe same, on an enlarged scale, taken on the line :1; :e of Fig. 1 and looking in the direction of the arrows. Fig. 3 is a detail perspective view .of the base-block of the scraper-clamp, and Fig. 4 is a detail View of the end portion of the holder, having a lfile-` clainp substitutedfor the scraper-clamp.

In the said drawings the handle portion of the holder is shown as comprising a handle proper, 1, preferably of wood, and a handlebar 2, secured thereto and preferably provided with a handle grasp 3, which is knul-lcd or otherwise roughened to provide a better gri i for, the hand of the operator. The end of this handle-bar farthest from the handle proper, 1, is threaded, as indicated at 4, and the extremity of said handle-bar is prei'- erably provided with a cup-like socket 5, having the shape of a portion of a s here. Upon the threaded end ofthe hand e-bar there is mounted a cap-sleeve 6, internally threaded, so as to screw upon the threaded portion 4 of the handlebar 2. The outer end of this capsleevc has formed in its interior a socket 7, having the form of a portionof a sphere, the wall of this socket being slotted, as indicated at 8,from the extremity of the rounded end of .the cap back to the cylindrical body portion of the same, where the slot terminates in an enlargement or circular opening 9, formed laterally' in thecap-sleeve. The sleeve 6 is also preferably knurled or otherwise roughened as to give a better hand-grip.

Each of the tool-clam s employed in oonnection with the hand e portion just described is provided with a ball 10' of a size such as to pass readily through the opening 9 and fit within the spherical socket 7 in the end of the cap-sleeve, said ball being connected with the tool-clamp by a neck 1 1, which is of a diameter equal to t-he width of the slot 8.

Various forms of tool-clamp may be employed in connection with the holder proper,

and in Figs. 1, 2, and 3 we have shown a toolclamp ada ted to hold a scraper or scrapingblade. Tis tool-clamp` comprises `a bascplate 1.2, towhich the vneck 11 issecured or with which it is formed in one piece together withtheballI 10. This base-plate provides the fixed jaw of the two clamping-jaws, and to; this end it is provided `at that niargm thereof farthest fromthe devices connecting it with the handle portion with 'a seat or cutaway portion 13 of less'depth than the thickness of the scraper-blade, which is' indicated at 14, said seat terminating in a shoulder 15,

against which one end ofthe scraper-bladeabuts when in place. The base-plate is further provided With a seat orcut-away portion 16, terminating in a shoulder 17 and adapted to receive the clamping-plate 1S, which forms the movable jaw. One edge of thisclam inglate abuts against the shoulder 17, wliile tlie opposite edge is coincident .with the outer edge of the seat 13, the top of the clamping-plate being flush withthe top of the base-plate 12. Said base-plate is relieved or cut away between the seats 13 and 16, as indicated at'19, and through this portion of the plate there are formed threaded apertures 20 to receive clamping-screws 21, which pass loosely through the clampingplate 18, in which their heads are countersunk, and upon which plate said heads bear in such away as to cause the. clamping-plate 18 IOO ` blade.

The scraper-blade preferablyr has each of its margins formed into a working edge, so that said blade constitutes, in eiiect, a plurality of scrapers,'which may be successively used until worn out. Said edges may be beveled at different angles to suit different kinds of work. Their angular relations to each other may be varied, and they may be straight orcurved, as desired. i

lt will iirst be noted that the scraper-blade 14 is readily detachable, it being necessary.

only to loosen the clamping-screws 21 to vpermit the removal oi the scraper-blade and the insertion of another blade or the reinsertion of the same blade, so turned as to present a different or new working edge, the clampingscrews when tightened up serving to firmly clamp the blade in position. It will be further seen that the angular relations of the tool-clamp and blade to the handle portion oi the device may be varied throughout a wide range. In the first place, the blade and holder may be moved from.. the position shown, in which the blade is axially in line with the handle-barret the holder to a position at right angles thereto, in which the blade is in a plane at right angles to the lonritudinal` axis of the handle portion. Furthermore, when in this latter position the blade may be so turned that vits plane may be. either transverse to the longitudinal axis of the handle portion or coincident with said longitudinal axis. Any intermedi-ate angle of adjustment in these two relations may be obtained or any combination of the two anguiar adjustments, thus giving the blade all desired possible relations to the handle portion. These adjustments are effected in an obvious manner by unscrewing the capsleeve 6` su'tiiciently to release the ball 10 from the grip with which it is held in thesocket 7 by the end of the handle-bar 2, whereupon said ball may be rotated around -an axis at right angles to the axis ofthe neck 11, said neck moving through the siot 8 during this adjustment, or said ball may be turned around an axis coincident with they longitudinal axis of the neck 11, or a combined movement around both axes may be eiiected. After the adjustment is effected the parts are clamped in position by screwing the cap on the threaded portion of the handle-bar until this latter clamps the ball iirmly in the osition to which it is adjusted. Finally, it wi l be observed that the' ca may be unscrewed until the end of' the han le-bar clears the opening 9, whereupon the toolclamp may be detached from the handie porsamen tion by withdrawing the ball 10 through the opening yQ. This not only forms a ready means of disconnecting the tool-clamp when it is desired to do so, llout it also provides a means for a'dapting the handle portion for use with tool-clamps designed for holding tools of different characters. As an illustration of this we have shown in Fig. 4 a toolclamp 22 havin a ball 23 and neck 'la identical with the all 10 and neck 11 of the scraper-clamp. This tool-clamp 'ZZ is designed to hold a ile 25 or other similar working tool or instrumentailty having a working surface as distinguished Jfrom a working edge, having for this purpose clamping-jaws 26, which are operated by a clam ing-screw 27. We make no claim to the ile-holding clamp in the present ap lication, however, as the same forms the subject-matter of another application iled by us of even date herewith.

It is obvious that a number of tool-clamps of different character may thus be employed with the handle portion of our improved tool-holder, one being readily substituted i'or another and the one in usebeing held in any desired angular relation to the handle portion.

We do not wish to be understood as limiting ourselves to the precise details of construction hereinbefore described and shown in the accompanying drawings, as it is obvious that these details may be varied without departing from the principle of our invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A tool-holder comprising a handle por- `tion having a handle-bar threaded at its extremity, a cap-sleeve threaded to fit the same, having a terminal socket, and slotted from its end longitudinally, said slot terminating in a lateral opening, in combination with a tool-clamp having a ball adapted to pass through said opening and it said socket, and a neck connecting said ball with the toolclamp and passing through said slot, substantially as described.

2. A tool-holder comprising a handle portion, in combination with a tool-clamp, said tool-clamp bein adjustable from a position in alinement wit said handle portion to a position substantially at right angles thereto, said tool-clamp being also adjustable around an axis extending centrally thereof transversely to the working edge of the blade, substantially as described.

ln testimony whereof we alix our signatures in presence of two witnesses.
